Len that is most instructive. The in-camera correction looks pretty damn good, and appears to be linked to lens and aperture. It's rather a pity that (for non CNX2 afficianoados) that it only shows up in the JPEG shots as third party RAW converters won't pick it up. Mind you it's not hard to fix this in Aperture as I am discovering, and I quite often add a bit of vignette to a final image anyhow.
I will be shooting JPEG for sports though, especially as my VR I 70-200 is a notable darkener of corners. It would be a shame to use JPEG for much else though, as the greater depth of the D600 RAW images fairly jumps off my iMac.
I wonder if the camera compensates for vignette it reduces exposure by half a stop or so and then darkens the centre and lightens the corners, or if this is just done through corner lightening with exposure unadjusted? And how would this all work if active dynamic range was pulling exposure in the opposite direction. Maybe it's just easier to either shoot RAW or stick to green button auto?
